Effect of Gamma Radiation on Electrical Properties of Bi1-xCaxFeO3 Multiferroic

Bi1-xCaxFeO3, (0.0 x 0.4) (BCFO) multiferroic samples were prepared in single phase using flash auto combustion method. Investigation of dielectric constant and ac conductivity of the samples was carried out. Frequency dependent dielectric constant, dielectric loss and ac conductivity measurement from 102 106 Hz at room temperature shows usual dielectric dispersion behavior before and after gamma-irradiation. The results promote the use of the gamma-irradiated multiferroics in high frequency applications.
